GB/T 38127-2019Articulated systems and flexible systems for cable guiding (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafting method to modify the use of IEC 62549.2011 "Hinged and Flexible Cable Management System for Cable Guidance".

The technical differences between this standard and IEC 62549.2011 and their reasons are as follows.

--- The first paragraph of Chapter 1 "Scope" was amended to read "This standard specifies a hinged and flexible cable management system for cable guidance.

General requirements, general conditions of testing, classification, marking and documentation, dimensions, structure, mechanical properties, electrical properties, flame effects,

External influence, electromagnetic compatibility. "

---About the normative reference documents, this standard has made technical adjustments to adapt to China's technical conditions, adjustments

The situation is reflected in Chapter 2, "Regulatory Citations", and the specific adjustments are as follows.

* Replace IEC 60529.1989 and its Modification No. 1 with GB/T 4208-2017 equivalent to the international standard (see

6.5, 7.4, 10.3.1, 13.1.2.1, 13.1.3.1, 13.1.4.1);

* Replace IEC 60417 with GB/T 5465.2 equivalent to the international standard (see 7.4);

* Replace IEC 60695-2-11.2000 with GB/T 5169.11-2017 equivalent to the international standard (see 12.1.2);

* Replace IEC 60670 (all parts) with GB/T 17466 (all parts) modified to international standards (see 3.6, 3.7,

4 5.3, Appendix A).

This standard also made the following editorial changes.

--- Add reference GB/T 2900.73-2008.

This standard was proposed by the China Electrical Equipment Industry Association.

This standard is under the jurisdiction of the National Electrical Equipment Standardization Technical Committee (SAC/TC67).
